what is created when vertebral bones are connected

intervertebral foramen

primary curve

develops before birth

secondary curve

develops after birth

what are the primary curves

thoracic and sacral

what are the secondary curves

cervical and lumbar

cervical curve

balances weight of head on vertebrae in neck

thoracic curve

provides room for thoracic organs

lumbar curve

balances weight of trunk over lower limbs, develops with ability to stand

sacral curve

provides room for abdominopelvic organs

what does axis have that allows you to turn your neck

dens

atlas parts

anterior arch, transverse process, transverse foramen, superior articular facet for occipital condyle, posterior arch, posterior tubercle, facet for dens of axis

axis parts

dens, superior articular facet for atlas, spinous process, transverse process, transverse foramen, body

when atlas and axis are together
